“Everything is good,” Teresa tells In Touch of her recent reconciliation with Melissa. She even admits to the mag, on newsstands now, that she’s “very confident” she and Melissa will stay on good terms.

Of the feud and surrounding drama, Teresa insists, “You have to let things go.”

As In Touch previously reported, the two were spotted "laughing and joking" together at a Milania Professional Hair Care event on Feb. 18.

Even Melissa’s husband, Joe — who has trashed his own sister Teresa while standing up for his wife in the past — seems to have had a change of heart. “She’s my sister and I’m always openhearted,” Joe tells In Touch.

So why now after four months of silence? According to a RHONJ source, the women were able to “hash things out” during a cast retreat in Lake George, N.Y., on Feb. 11. While things are far from perfect, they’ve agreed to bury the hatchet for the sake of their children. "They realized it takes too much energy to keep fighting the way they were,” says the source.
